To all whom-it mag concern.-

Be it known that we, ROBERT JAMES RUD- ALL, patternmaker, residing at.31 Cambrian Street, Llanelly, Carmarthenshire, Wales, and THOMAS BROWN,fitter, residing at 3 Glanmoor Terrace, Llanelly, aforesaid,- and JOHNHUGHES WiLLrAMs, bootm'akenriasiding at Liverpool House, Bynes, nearLla- Iielly aforesaid, all subjects of the King of Great Britain,haveinvented a Tool-Handle Fastening, of which the following is aspecification. 1

This invention relates to an "improved method of and means for securinghandles or shafts to the headof picks, hammers, and the like. v

According to this invention the handle or shaft (hereinafter referred toas the handle) is provided with an enlarged head end or formed larger atone end, and is adapted to fit in a stout metal socket having the boreor interior thereof tapered orshoiildered or otherwise formed larger atone end than at the other end; and the head end of the'hanthe is fittedin this socket so as to become wedged therein and is advantageously madeto fit accurately in this socket; and the head of the pickaxe or hammeror the like isthen placed across the larger end. of the socket with thehandle wedged therein and is-secured thereto by a clip of U-shape orequivalent which embraces the head and fits ina recess therein toreceive same, while the arms of the U-shaped clip extends downeach sideof the head end of the handle inside the socket e. between the exteriorofcthe en'- larged head end of the handle and the interior wall of thesocket) and are securely the like thereby firmly secured to the handle.

Furthermore this invention comprises other features and details all ofwhich-will be hereinafter fully described with reference to theaccompanying drawings and finally pointed out in the claims.

In the accompanying drawings we have illustrated the present inventionas carried into practice for securing the head of a pick to the handletherefor.

Fig. 1 is a side view in elevation of a pickaxe-such as used in coalmines-having the head secured to the "handle with the present invention.Fi 2 is a perspective view of the socket alone. i

Fig. 3 is a perspective View of the U- shaped clip alone.

Fig. 4 is'a cross sectional view onthe line in accordance a -4. Fi .i.Fig. 5- is a local vertical sectional 'view on a somewhat enlargedscaleon the line A is the handle to which the head of the pick is,secured according to this invention,

such handle being provided with an enlarged tapering head end A Bis thestout metal socket the interior bore ofwhich is tapered correspondingly,to the tapered enlarged end A of the handle. C is the U-shaped clip, thespring arms C of which pass down inside the socket B and areeachzprovided with an enlarged endC adaptedto engage in the recess Bformed oneach side of the lowerend of the socket B. These recessesB areformed opposite to one another in the oppositeside faces of the socketB; while at the top end of the socket B same is slotted Vertically at Bto permit the underside of the head D of the pick to fit insaid slot sothat said under part of said head is embraced or lies between the frontand back topside edges B of the socket B.

The outeredge of the head D of the pick as shown is providedwith acentrally located recessD? for the bent portion of the U-shapedclip O toseat or fit in said recess and thus lock and hold the head; end againstendwise displacement of said head- The underside edge of said pick isprovidedflwith two separate slots or recesses I) (see Fig. 6) adapted toengage and fit down over the top edge of the socket B (when slotted at Bas shown in Fig. 6. The interior wall. of the socket B is provided withoppositely disposed vertical grooves B Fig. 2 and the enlarged head endA of the handle is provided with correspending grooves to permit thearms C of the clip (3 to be passed down inside the socket B between theinterior thereof and. the exterior of the head end A of the handle A.

The parts are fitted together as follows The smaller end A of the handleA is passed into the larger end of the socket B and the handle A passedthrough said socket until the larger end A becomes wedged in theinterior of said socket as shown in Fig. 6.

The head D of the pick is thencentrally placed transversely across thelarger end of the: socket B with handle A therein, as shown in Figs. 1and 6 and the arms C of the clip C are then passed down each side of thehead D and threaded down the aforesaid grooves inside of the socket B oneach side of the head A of the handle A (i. e. be tween the head A andthe inside wall of the socket B) until the enlarged head end C of eacharm C sprin s outwardly into and engages in the slots whereupon thewhole of the parts are securely attachedtogether and thus the head D ofthe pick is firmly secured to the handle A. I

If it he desired, incident to probable shrinkage of the handle A, thesocket B may be secured to the handle by a rivet, screw, nail or othersuitable device, which may pass in an edgewise direction through thesocket and'handle to insure the retention of the socket in place.

It will be obvious that various modifications could be made withoutdeparting from the scope of this invention; for example the socket Bcould be made without the slots B therein in which case the arms G ofthe spring clips G would then be made longer and the enlarged head endsC engage the bottom edge of the socket B. If desired the head end of thehandle could be fastened by any suitable means to the socket instead ofor in addition to being a tight fit but always in suchwise that the headend of said handle cannot be drawn through the said socket.

What we claim is: I

1. The herein described means for securing the head of a pick, hammer,or the like to the handle therefor; comprising a handle having the headend thereof tapered and said tapered portion being larger incrosssectional area than the remaining part of said handle, a stoutmetal socket having the bore thereof tapered as a counterpart to saidtapered head end of the handle, a tool head having slots on theunderside thereof adapted to engage with and it down over the top edgeof the aforesaid socket at opposite sides thereof, said. head of thetool having a recess in the top edge thereof, a sprlng clip of invertedU-shape adapted to embrace said head and fit down in said recess thereinand the arms ofsaid clip adapted to pass down the opposite sides of thehead of the handle inside said socket, said socket hav ingoppositelydisposed grooves extending lengthwise thereof to receive the arms ofsaid clip, and means on the outside of the socket having the bore orinterior thereoftapered as a counterpart to said tapered head end of thehandle, said metal socket having oppositely disposed slots in the topedge of the larger end thereof located in such wise as to permit theunderside edge of the head of the tool to lit in said oppositelydisposed slots so that the top end of the socket will embrace the sidefaces of said head when all the component parts are assembled and fixedin position, a tool head having; slots on the underside thereof adaptedto engage with and fit down over the top edge of the aforesaid socket atopposite sides thereof, said tool head having a recess on the top edgethereof, a spring clip of inverted U-shape adapted to embrace said headand fit down in said recess therein and the arms of said clip adapted topass down the opposite sides of the head of the handle inside saidsocket, said socket having oppositely disposed grooves extendinglengthwise. thereof to receive the arms of said'clip, and n'icans on theoutside of the end of each of the arms of said clip adapted to pass downsaid grooves inside said pocket and to en gage the lower end of saidsocket for locking and holding all the aforesaid components in position.
